To all whom it may concern Be it known that I, WILLIAM T. GIBERSON, acitizen of the United States, residing at Toms River, in the county ofOcean and State of New Jersey, have invented certain new and usefulImprovements in Reclining- Chairs, of which the following is aspecification.

This invention relates to chairs, and more particularly to recliningchairs which may be operated to effect a change in inclination of theback and leg rest thereof by the user while seated in the chair, by thesimple shifting of a lever.

The object of the invention is to provide a reclining chair having fewparts, simple in construction and operation and inexpensive tomanufacture, and in'which the back and leg rest may be simultaneouslyadjusted by a hand lever operated by the occupant of the chair whileseated.

The invention consists in a chair having a frame supported upon legs inthe usual manner, a back and a leg rest hinged thereto, arms pivotedthereon and connected with the back and a system of levers and linksconnecting said back and" leg rest whereby they may be shiftedsimultaneously at the desire of the user while seated in the chair.

In the accompanying drawings, illustrating the invention, in the severalfigures of which like parts are similarly designated:

Figure 1 is a side elevation.

Fi 2 is a central vertical section and showing in dotted lines thepositions of the various moving parts when adjusted for reclining.

Fig. 3 is a front elevation.

Fig. 4 is an enlarged perspective view of the lever and link operatingmechanism.

Fig. 5 is an enlarged perspective view of one of the arm attachingsockets.

'Fig. 6 is an enlarged perspective view of one of the caps for the upperends of the le s.

Fig. 7 is a perspective view of one of the hinges of the back.

The frame of the chair comprises a seat frame 1 provided with a cushion,or otherwise suitably upholstered, supported upon front legs 2 and backlegs 3, the legs being connected near the floor in the usual manner byside rails 4, a front round 5 and a back round 6.

The back of the chair comprises side rails 7 a top 8, an intermediatespacing member 9 and a bottom connecting rod 10, and the space betweenthe top 8 and member 9 may be provided with "slats 11 to support acushion or other upholstering. The back is hinged to the chair frame byhinges 12, one part 13 of each of which is attached to the side rails ofthe back and the other part 14 to the backs of the back legs 3 so thatthe hinge pintle is approximately in line with the top surface of theseat frame 1.

The side rails 7 of the back are extended a considerable distance belowthe seat and beyond the round 6, nearly to the bottoms of the chairlegs, and upon the inside of the rear legs 3 of the chair, and when theback is moved to its upright position said side rails 7 en age the backround 6, as clearly shown in l ig. 2.

The upper ends of the front legs 2 are provided with pivot bearings 15and the back legs are provided with similar pivot bearings 16. I havehere shown these pivot bearings as metal caps (Fig. 6) which may beapplied to the upper ends of the legs, but it is obvious that thebearings may be formed integral with the legs. In the bearings 15 and 16are pivoted the lower ends of link extensions 17 and 18, respectively,the upper ends of which are pivotally connected with the arms 19 and 20-at front and rear, respectively. Here again I have shown metal sockets21 and 22 (Fig. 5) for the bearing pieces of the pivots, but it isobvious that the bearings-might be'made integral with the arms.

The extensions 18 of the legs 3 are provided with links 23 which serveto connect them with the side rails 7 of the back to cause the arms tomove with the backto position themwith proper relation thereto,irrespective of the inclination of the back, the two sets of pivotedlinks or leg extensions 17 and 18 at front and rear, serving to maintainthe arms in substantial parallelism with the plane of the seat, in anyadjustment of the back.

A leg rest is suitably hinged at 24: to the seat frame 1 at the frontand this leg rest has side members 25 and top and bottom members 26 and27 respectively, and covering slats 28.

Mounted in suitable hearings in the seat frame 1 is a shaft 29 whichextends out beyond the side of the frame at one side, and about midwayof its length between the sides af the frame a lever arm 30 is pinned,or otherwise fixedly secured to it, to turn with it. To the lower end01": this arm 30, at a single point, are pivotally attached the links 31and 32 connected, respectively, with the rod 10 at the lower extremitiesof the back rails and arod 33 mounted in'suitable brackets 3-lsecured tothe side members 25 of the leg rest at 'a point preferably below thehorizontal center line "of Ttlle :leg PIESD.

On the extended end of the shaft 29 is mounted a hand :lever 35 by whichthe shaft 29 :may be oscillated, and this 'lever is provided with a pawl36 which "coaet's with a ratchet sector 37 to lock the lever in anydesired position.

In orderto take the strain 'of the back oil of the lever and linkmechanism when the parts are in the extreme reclining iposition, stops38 areiprovided upon the frame with Which the side members '7ofthei-backcoact, as shown in the 'dotted line position, Fig. 2. Themovement 'of the *back in the ropposite direction is limited by theround 6 against which'the side members 7 abut.

The chair is preferably made of avooch' but the parts '10, 29,30,'31,=32, s3, 34, 35,36and 37 are :matle preferably of metal in tlieinterest of rigidity and to resist wear.

I 'have 'shown indotted lines,'l?ig. -'1, a foot rest which may or maynotbe"hinged to'the leg =rest.

It will be observed that by the particular arrangement-and location ofthe connecting links 31 and 32 with the back andleg rest,

respectively, and the connections of the said 'links at a single pointwith the operating lever 30, a very easy operation of the :parts isobtained, and "there is no possibility of the parts coming on adead-center and locking the parts against operation.

I do not wish "to'be understood as limiting my invention to the variousdetails of construction and arrangement of parts as shown in thedrawings, it being obvious'that various changes may be made thereinwithout departingfrom the spirit o-f'the invention or thescopeoftheappended claims.

What I claim is:

1. A chair of the character described, comprising a'frame and aseattherein,legs for supporting the'trame, a back and a leg rest hingedto said 'frame in substantially the plane ofthe seat,'andsaid backhaving side rails exten'dingbelow said seat to near the bottoms of thelegs, a rock-shaft mounted insaid frame, means connected with the shaftto operate it from the seat, a lever arm fixed to said rock-shaft andextending below-the seat to a point above the lower ends of the backrails and substantially centrally of the 'legrest, and links pivoted ata single point to the extremity of said lever arm at one end, and one ofsaid links p'ivotallyconnected to the leg rest below the horizontalcenter thereof, and the other link pivotally connected to the lowerextremity of the back rails, whereby when said 'IIQQk-Qhait isoscillated the :back and leg rest will :bemoved simultaneously.
